is also provided'with asafetytube containing water or other `fluid, so that in case the stopproper time the gasometerwill relieve itself; but to secure the `closing of said stop-cocks when nearly full and the stopcocks by meansv of a lever or cord. l

For a portable gas-works I make the retort aboutthirty inches long and four inches diameter'inside, and place it in the center of 'a small box-stove by means of openings in the end ot' theI stove. This stove is abouttwenty inches and twelve inches cooking purposes7 so that the gas required for an evenings-use may be made with the same heat thatcooks the meals; but I do not limitthe size ofthe retortor confine myself to any particular method of mounting it, the process bcv ing adapted to much larger operations.

My method of operating is as lfollows: I charge the retort`with small billetsof wood,

preferring those kinds of wood which yield by d destructive distillation a considerable quantity of gas. Having secured the cap at 'the end of theretort, I kindle the re and bring the retort to a bright-red heat. red heat l a considerable quantity of wood-gas will have passed `into the gasometer and the' Vwood be converted into charcoal. The two stop-cocks in the feed-pipes are now to be opened,whentbe eil and water,in due proportions, willilowinto the retort. The oil undergoes destructive distillation and forms a very `rich oleant gas', and the oxygen of thewater being absorbed by the red-hot carbon, producingcarbonic oxide,its hydrogen is set free. The

result isa carbureted hydrogen at avery low cost to live hundred cubic feet of exceedingly lu mi nous gas in the use of one gallon of oil, whereas y the same amount of oil alone wouldyield but one hundred feet. uI can use in the process any good gas, oil,or grease; but I prefer the heavyor paratiine oil of coal or petroleum.

` In the accompanying drawing A andB rep` resentxthe stove 'and the retort as mounted.

The holes are in the top end of feed-pipes, and the wires run through these holes and project upward through the top ofthe can, so that they can be pushed up and down in case of clogagge. The size of the wires relatively to that ofthe holes regulates the amount of flow.

The cap of the retort is marked G. The boiler-openings of the stove are marked H H, and Iindicates thesmokepipe.

J J is the discharge gas-pipe, provided with a valve, K, to preventa return of gas into the stove in case of a fracture of the retort.

L is the service-pipe, and M the levcr for closing the stop-oocks N N. This lever has its fulcrum atO and is lifted by pin P, being so arranged that it shall be lifted just before the gasometer is full. A cord or chain may be used instead of the lever. y

I do not claim,in the abstract,any portion of the above-described apparatus. Neither do I claim the use ofyvood-charcoal at a red heat for decomposing Water or oil. The use of wood, however, for the triple purpose of making Wood gas, gasifying oil, and decomposing water I believe is new, as is also my method of i charging the retort-viz.,with Wood instead of charcoal-and thus securing the advantages of having the charcoal freshly burned,and finding a recompense for thc slight trouble in the woodgas obtained; and not only in the amount of the latter, but in the fact that its presence with the other gases is highly beneficial. I would further state that I can omit the wood and oil and substitute for both bituminous coal, in

which case I depend upon the incandescent coal and coke for decomposing the water.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination of Woodgas, the hydrogen of Water,aud the gas of paraifineoil, or the same combination with any other oil-gas or the gas obtained from bituminous coal, when effected in the manner substantially as described, wishing, however, to be distinctly understood that I make no claim to wood, water, or oil gases in the abstract, knowing that they have been produced by others, but that I claim the methods described forproducing and uniting the same, with a view to convenience, cfcicncy, and economy.
